Benefits of technology

This patent describes methods for creating conductive structures by coating elongated substrates with carbon nanotubes and then reducing the size of the substrate. The technical effect of this is the creation of thin, flexible, and conductive materials that can be used in various applications such as electronics, sensors, and energy devices.

Problems solved by technology

The conductivity of these materials can be improved by increasing the amount of material (e.g., by increasing the wire diameter), but such increases in conductivity are normally accompanied by increases in weight and expense.

Abstract

Provided are composites that exhibit improved conductivity characteristics as compared to existing conductors. The disclosed conductive composites include a substrate—e.g., a wire that is surmounted by a coating of carbon nanotubes. Substrates may be metals, ceramics, polymers (conducting, non-conducting, and semiconducting) The composites may also include metallic, ceramic, or polymeric materials—such as nanoparticles—that are disposed on or even disposed within the nanotube coatings. Also provided are related methods of fabricating the disclosed composites.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present application is a national phase filing of PCT application number PCT / US2014 / 00131, with an international filing date of May 23, 2014, which claims priority to and the benefit of U.S. nonprovisional patent application No. 61 / 827,168, entitled “Carbon Nanotube Composite Conductors” and filed May 24, 2013, the disclosures of which are each incorporated herein by reference in its entirety for all purposes.BACKGROUND[0002]1. Technical Field[0003]The present disclosure relates to the field of carbon nanotubes and to the field of composite conductor materials.[0004]2. Description of the Related Art[0005]Conventional conductor materials (e.g., wires) can be heavy, particularly in the case of conductive materials as copper, steel, and other metals. The conductivity of these materials can be improved by increasing the amount of material (e.g., by increasing the wire diameter), but such increases in conductivity are normally accompanied ...
